Butterfly Valves

To ensure the safety and effectiveness of butterfly valves, a series of meticulous performance tests are conducted. These tests focus on sealing and pressure performance and include API 598 compliance, and API 6D standards.

When manufacturing butterfly valves, we also focus on raw material inspection to improve the durability and reliability of butterfly valves. This ensures that they are suitable for use in harsh environments. 

For example, low-temperature impact testing (typically at 60 degrees) simulates challenging conditions to verify material resilience. In addition, X-rays are used to detect any internal defects that could compromise the integrity of the valve.

Our butterfly valves are subjected to a final butterfly valve inspection prior to shipment, which is an important step in ensuring that each product meets quality standards and customer expectations. 

This process begins with a detailed inspection of the valve surface to ensure a flawless appearance.

The rest of the process consists of:

• Dimensional verification (precise measurements are taken to confirm that the valve meets the specified dimensions.)

• Coating and Paint Evaluation (Paint is scrutinized for uniform coverage and adhesion to ensure aesthetics and corrosion resistance)

• Packaging and labeling review (Proper packaging is critical for safe transportation. The inspector confirms that packaging materials are appropriate

  and accurately labeled with important information such as specifications and operating instructions.)

Our commitment is to provide high-quality products that meet or exceed industry standards for reliability and durability. And we guarantee to produce only the best and highest quality products for our customers.

All of our valve products undergo two quality inspections. We are equipped with an independent quality control laboratory to take responsibility for the quality of all our products, 

and we offer free replacement for quality problems within 2 years from the date of purchase, which is a clear indication of the confidence we have in our products.

This dual focus on compliance and quality ensures that our butterfly valves not only perform reliably, but also meet the highest safety standards. By combining strict international compliance with a strong quality assurance policy, 

we offer our customers unrivaled peace of mind.
